Specification of Letters Patent.

To all whom "it may concern Be it known that 1, WILLIAM F. Bonn, a citizen of the United States, residing at Mountain View, in the county of Santa Clara and State of California, have invented certain new and useful Improve.- ments in Triple Offsets for Plows, ofwhich the following is a specification.

My invention relates to triple offsets for,

plows and more particularly to that general class of plows known as orchard plows.

The object of the invention is to provide a triple offset for plows of simple and durable construction, capable of being used in orchards for plowing close to the trees, or in any other place where close plowing may be required. 7

A further object is to provide a triple offset for plows that may be attached tov the plow beam of a plow and quickly re-- moved when not required, and an offset that may be quickly adjusted as the operator may rec uire.

Figure 1 is a plan View of plow beam and,

triple offset and chain attached thereto.

Fig. 2 is a perspective view of offset at plow end of beam.- Fig. 3 is a detail view of the eye-bolt. v

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same characters.

The improved triple offsets for plows forming the subject matter of the present invention, comprises an angle iron offset 1 of the required length, width and thickness having upturned flanges as 2. These flanges are for the purpose of strengthening the plow beam and are a part of angle iron offset 1. Said angle iron offset 1 has a brace fastened thereto as shown at 3, said angle manner.

iron offset- 1 beingfastened to the under side of plow beam 4 near the plow thereof by bolts shown at 5. Near the outer end of angle iron offset 1 isshown a hole bored through said angle iron ofiset 1 at 6 into which a draft chain 7 orwire rope is fasoffset hole 13 bored in offset plate 11. Said angle iron ofi'set 9 is made-of iron or steel of the required length, width and thickness, and is fastened near the outer end of plow beam 4 by bolts shown at 14: the oflset porarr curios.

tened. Said draft chain or wire rope 7 extends forward and under plow beam 4 and tion thereof having a plurality of holes 15 Y bored therethroughfor the purpose of adjusting the ofiset required at this point by inserting therein eye-bolt 8 through which chain or wire rope 7 passes. Ofiset plate 11 may be made of iron or any other suitable material of the required length, width and I thickness,having holes bored through the samenear the ends thereof as shown at 16 which are for the purpose of connecting offset draft chains 17 to draw bar 18, the inner chain being shorter than the outer chain for the purpose of offsetting swingle-tree 18. Said chains are connected with swingle-tree 18 near the ends thereof in any suitable of wood or any other suitable material of the required width and thickness and of any length that may be required as it is often found that three or more horses may be worked abreast to advantage. to swingle-tree 18 by clevises 19 are shown whifiletrees 20, to which horses are attached.

My improved device is simple in construchis swingle-tree 18 maybe made Connecting tion, can be secured to any ordinary plow beam, is of few parts, and can be manufac-' tured at a small initial cost.

It is evident that slight changes in the construction of the different parts might be resorted to without departing from the spirit of my invention, and hence I would have it understood that I do not limit myself to the exact construction shown and described, but consider myself at libertyto make such slight changes and alterations fairly fall within the spirit and scope of my invention.

Having fully described my invention,

"what I claim as new and tion of an angle iron ofiset having upturned flanges thereon and a brace attached there- 10- under said plow beam, an angle iron offset 3 fastenedon thetop and near the outer end ,7 of saidplow beam a plurality ofholes bored through said ofiset portion of said angle I iron adapted toengage an eye-bolt through (Epics ,of this patent may be'obtained for five cents each, by addressing 't v Washington, D. 0.? p I desire to secure by Letters Patent, is J 1 In a triple offset for plows; the c'onibin'a which a ehain or wire rope passes connecting, with an offset plate to which is connected at its ends by ofiset draft chains of different lengths, said *ohains' connecting with a,sWingle-tree,' means by which said sWingle-tree is connected to Whiffletrees as and for the purposedescribed.

In testimony whereof I affix my signature 5 inpresence of two subscribing WitnessesQthis 9th day of April, 1914.
